Which component of an operating system allows the operating system to run applications?

The file manager is a component that helps users manage files on the system, including creating, deleting, and organizing files and directories. While it plays a crucial role in user interaction with data, it does not directly enable the execution of applications, which is the primary function of the kernel.

Drivers are specialized software that enables the operating system to communicate with hardware devices. Although they are essential for the functioning of hardware components, they do not provide the core functionality required for running applications, which is the responsibility of the kernel.

The user interface (UI) is the means by which users interact with the operating system and applications, providing graphical elements or command-line access. While important for user experience, the UI itself does not facilitate the execution of applications; this task is managed by the kernel.
